JOSEPH P. MANTON, OF PROVIDENCE, RHODE ISLAND.

SHIPS WINDLASS.

SPECIFICATION forming part of Letters Patent No. 569,110, dated October 6, 1896.

Application filed August 19, 1895- Serial No. 559,833. (No model.)

To all whom it may concern:-

Be it known that I, JOSEPH P. MA vroN, a

' citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Ships Windlasses, of which the following is a specification.

My invention relates to a ships Windlass operated by steam-power; and it consists in certain improved details of construction, as hereinafter fully set forth.

In the accompanying drawings, Figure 1 represents a partial side elevation of a ships Windlass provided with my improvement.

Fig. 2 represents a partial end elevation with portions broken away to show the hidden parts. Fig. 3 represents a vertical section taken in the line 3 3 of Fig.1. Fig. 4 represents a detail side elevation and partial section of the wildcat and the clutch. Fig. 5 represents an enlarged detail section showing a top View of the clutch for engaging and disengaging the capstan-shaft. Fig. 6 represents an enlarged side view and partial axial section, taken in the line 6 6 of Fig. 5, showing the bevel-pinion and the clutch mechanism which serves to operate the capstan-sh aft, the said shaft being in the figure turned from its vertical to a horizontal position. Fig. 7 represents. an enlarged end view, and Fig. 8 a side view, of the clutch-head employed on the capstan-shaft. Fig. 9 represents an enlarged top view of the pinion on the capstan-shaft. Fig. 10 represents an enlarged top view, Fig. 11 an end view, and Fig. 12 a side view, of the covering-cap employed to fill the space between the worm on the driving-shaft and the bearing-box.

In the drawings, A represents the bed-plate of the Windlass, B the central upright standard, which forms a bearing for the shaft 0, and D one of the end bearing-standards. The similar bearing-standard for the opposite end of the shaft 0 is not shown in the drawings. The cap E of the bearing-standard B forms a step a for the upright shaft F of the capstan, the said shaft being provided with the adjustable collar 1), above which is placed the loose bevel-pinion G, which serves, in conjunction with the bevel-gear on the Windlassshaft, to transmit rotary movement to the capstan-shaft, the said pinion G being thrown into and out of engagement with the capstanshaft by means of a clutch arranged upon the shaft F above the pinion G, the said clutch consisting of the clutch-head c, keyed to the shaft F and provided with the longitudinal flanges M and the intermediatelongitudinal grooves cl cl, the said groovesbeing adapted to receive the sliding clutch-bolts e e, which engage with the inwardly-projecting lug portions ff at the upper side of the pinion G. The sliding clutch-bolts e e are provided with the notches g g, the said notches being engaged by the inclined cams h h, which extend partially around the inner side of the annular shell H, the said shell being provided with the hand-rim '6, by means of which a partial revolution may be imparted to the shell H over the clutch-head c. The shell H is supported for revolution by means of its bearing upon the outer faces of the flanges 1' 1' and upon the flange s of the annular plate I, which is secured to the clutch-head 0, so that upon the movement of the annular shell H in the proper direction the sliding bolts 6 e may be thrown into or out of engagement with the clutch-lugs ff of the pinion G, and by means of this hand-operated clutch mechanism motion maybe imparted from the Windlass-shaft C to the capstan-shaft F.

' Upon the shaft 0 of the Windlass is keyed the worm-gear J on the side of which is cast the bevel-gear K, which engages with the. pinion G on the capstan-shaft F, the said worm-gear being driven by means of the worm L upon the driving-shaft M, the said worm being held for revolution with the shaft M by means of the spline j. The worm L is adapted to slide upon the shaft M between-- the bearing-boxes N N, and is retained in its engaging position with the worm-gear J by means ofthe loosely-removable cap 0, which rests over the shaft M in the space between the end is of the worm L and the face of the bearing-box N, and upon lifting the cap 0 from its position over the shaft M the worm L may be thrown out of engagement with the worm-gear by sliding the worm upon the shaft M until it strikes the face of the bearing-box N. The Windlass can then be operated by hand, .being prevented from backward movement by means of the ratchet-wheel P, keyed to the shaft 0, and the pawls 25 t as usual. Upon the shaft 0 is keyed the clutch-head Q, upon the peripheral outer edge of which is placed the cam-ring R, the said ring being provided on its periphery with the inclined cams m m, which engage with the notches n n at the inner side of the sliding clutch-bolts S S, which are held in the clutch-head, the said ring B being held in position for movement on the clutch-head Q by means of the fiat plates 0 0, which are secured to the side of the clutch-head Q by means of screws.

The wildcat T of the Windlass is provided at its side with the projecting lugs U U, which are adapted to engage with the sliding clutchbolts S S when the said clutch-bolts have been brought forward by turning the camring R on the clutch-head Q, suitable openings p 19 being madein the periphery of the ring R for the insertion of a handspike for imparting the required rotary movement to the ring, the ring R being held in its set position by means of the friction-pad q, inserted between the plate 0 and the side of the camring R. The movement of the cam-ring will serve to effect the engagement and disengagement of the wildcat T relatively to the driven shaft 0.

I claim as my invention 1. In a ships Windlass, the combination of the worm-gear upon the Windlass-shaft, with the driving-shaft, and bearing-boxes, the slidable worm engaging with the worm-gear, and the removable cap resting over the shaft, in the space between the end 'of the worm, and the face of the bearing-box, substantially as described.

2. In a ships Windlass, the combination of the windlass-shaft C, and the loose wildcat T provided with the projecting clutch-lugs V, with the clutch-head Q, keyed to the Windlass-shaft, the cam-ring R, provided with the openings 1), the inclined cams m, upon the periphery of the oam-ring, the holding-plates 0 provided with the friction-pads q, and the sliding clutclrbolts S, held in the clutch-head Q, and provided with the notches n, for engagement with the operating-cams, substantially as described.
